CVE-2024-47776
📋 TL;DR
CVE-2024-47776 is an out-of-bounds read vulnerability in GStreamer's WAV file parser that occurs when processing malformed CUE chunks. This allows attackers to read beyond allocated memory buffers, potentially causing crashes or information disclosure. Any application using vulnerable GStreamer versions to process untrusted media files is affected.
💻 Affected Systems
- GStreamer
- Applications using GStreamer library
📦 What is this software?
Gstreamer by Gstreamer Project
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution through memory corruption leading to complete system compromise, though this requires specific memory layouts and exploitation techniques beyond simple OOB-read.
Likely Case
Denial of service through application crashes or information disclosure by reading adjacent memory contents, potentially exposing sensitive data.
If Mitigated
Application crash with no data leakage if proper sandboxing and memory protections are in place.
🎯 Exploit Status
Exploitation requires feeding a malicious WAV file to vulnerable GStreamer instances. No authentication needed if application processes external media.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 1.24.10
Vendor Advisory: https://gstreamer.freedesktop.org/security/sa-2024-0027.html
Restart Required: Yes
Instructions:
1. Update GStreamer to version 1.24.10 or later. 2. For Linux distributions, use package manager: 'sudo apt update && sudo apt upgrade gstreamer1.0' (Debian/Ubuntu) or 'sudo yum update gstreamer' (RHEL/CentOS). 3. Restart affected applications. 4. Recompile applications statically linked to GStreamer.
🔧 Temporary Workarounds
Disable WAV parsing
linuxRemove or disable gstwavparse plugin to prevent processing of WAV files
gst-inspect-1.0 --plugins | grep wavparse
rm /usr/lib/gstreamer-1.0/libgstwavparse.so
Input validation
allImplement strict file type validation and size limits for media uploads
🧯 If You Can't Patch
- Implement network segmentation to isolate media processing systems
- Use application sandboxing (seccomp, AppArmor, SELinux) to limit impact of crashes
🔍 How to Verify
Check if Vulnerable:
Check GStreamer version: 'gst-inspect-1.0 --version' and compare to 1.24.10. Versions below are vulnerable.Check Version:
gst-inspect-1.0 --versionVerify Fix Applied:
Confirm version is 1.24.10 or higher: 'gst-inspect-1.0 --version | grep "GStreamer"'📡 Detection & Monitoring
Log Indicators:
- Application crashes with segmentation faults
- Memory access violation errors
- Unexpected process termination when processing media files
Network Indicators:
- Unusual WAV file uploads to media processing endpoints
- Multiple failed media processing requests
